Abstract
The utility model relates to a cold rolling mill, in particular to a shell type cold rolling mill. The shell type cold rolling mill comprises a machine frame, an upper pressing roller, a lower pressing roller, an upper supporting roller, a lower supporting roller, couplers and transmission shafts. The upper pressing roller and the lower pressing roller are arranged on the machine frame. The lower pressing roller is located below the upper pressing roller. The upper supporting roller and the lower supporting roller are further arranged on the machine frame. The upper supporting roller is located above the upper pressing roller. The lower supporting roller is located below the lower pressing roller. The upper supporting roller and the lower supporting roller are fixedly connected with the transmission shafts through the couplers respectively. The upper portion of the upper pressing roller and the lower portion of the upper pressing roller are fixedly connected with an upper shell and a lower shell respectively. A gate is welded to the machine frame. The upper shell, the lower shell and the upper pressing roller are respectively provided with a screw hole. The upper shell and the lower shell are fixedly connected after a screw is screwed into the screw holes. The gate is fixedly connected with a magnet block through a threaded rod. According to the cold rolling mill, the pressing rollers can be easily and conveniently maintained and replaced, cost is reduced, and the effect is improved.
Description
Technical field
The utility model relates to a kind of cold-rolling mill, especially clamshell type cold-rolling mill.
Background technology
Cold rolling is that the blank providing taking hot rolling is rolling raw material, after pickling scale removal, carry out cold continuous rolling etc., mainly that any surface finish, dimensional accuracy are high through the products characteristics of cold rolling process, but because the frequent extruding of upper pressure roller of cold-rolling mill easily causes surface damage, need to change and just must change whole pressure roller, be unfavorable for saving maintenance cost.
Utility model content
In order to overcome existing cold-rolling mill deficiency difficult in maintenance, the utility model provides clamshell type cold-rolling mill.
The utility model solves the technical scheme that its technical problem adopts: clamshell type cold-rolling mill, comprise frame, upper pressure roller, lower compression roller, top backing up roll, lower support roll, shaft coupling and power transmission shaft, frame is provided with pressure roller and lower compression roller, lower compression roller is positioned at pressure roller below, in frame, be also provided with top backing up roll and lower support roll, top backing up roll is positioned at pressure roller top, lower support roll is positioned at lower compression roller, top backing up roll is fixedly connected with power transmission shaft by shaft coupling respectively with lower support roll, the top of upper pressure roller is fixedly connected with lower clamshell respectively at upper clamshell with bottom, in frame, be welded with gate.
According to another embodiment of the present utility model, further comprise on clamshell, lower clamshell and upper pressure roller and be all provided with screw, screw is realized being fixedly connected with of upper clamshell and lower clamshell by being screwed in screw.
According to another embodiment of the present utility model, further comprise that gate is fixedly connected with magnet piece by screw rod.
The beneficial effects of the utility model are that this cold-rolling mill safeguards that replacing pressure roller is simple and convenient, has saved cost, has improved effect.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. frames in figure, 2. go up pressure roller, 3. lower compression roller, and 4. top backing up roll, 5. lower support roll, 6. shaft coupling, 7. power transmission shaft, 8. goes up clamshell, 9. descends clamshell, 10. gate, 11. screw rods, 12. screws, 13. screws, 14. magnet pieces.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, clamshell type cold-rolling mill, comprise frame 1, upper pressure roller 2, lower compression roller 3, top backing up roll 4, lower support roll 5, shaft coupling 6 and power transmission shaft 7, frame 1 is provided with pressure roller 2 and lower compression roller 3, lower compression roller 3 is positioned at pressure roller 2 belows, in frame 1, be also provided with top backing up roll 4 and lower support roll 5, top backing up roll 4 is positioned at pressure roller 2 tops, lower support roll 5 is positioned at lower compression roller 3, top backing up roll 4 is fixedly connected with power transmission shaft 7 by shaft coupling 6 respectively with lower support roll 5, the top of upper pressure roller 2 is fixedly connected with lower clamshell 9 respectively at upper clamshell 8 with bottom, in frame 1, be welded with gate 10, upper clamshell 8, on lower clamshell 9 and upper pressure roller 2, be all provided with screw 12, screw 13 is by being screwed into being fixedly connected with of clamshell 8 and lower clamshell 9 in the interior realization of screw 12, gate 10 is fixedly connected with magnet piece 14 by screw rod 11.
First adjust the distance between top backing up roll 4 and lower support roll 5, top backing up roll 4 is pressed on pressure roller 2, lower support roll 5 is pressed on lower compression roller 3, then steel band is put between upper pressure roller 2 and lower compression roller 3, when the thickness of pressure roller 2 in needs adjustment or the upper clamshell 8 of upper pressure roller 2 or lower clamshell 9 damage, just only screw 13 need to be backed out, then change applicable upper clamshell 8 or lower clamshell 9, after shutting out between upper pressure roller 2 and lower compression roller 3, steel band can pass through gate 10, finally utilize screw rod 11 rotations to regulate, magnet piece 14 can be fitted on steel band, can adsorb the metal fragment on steel band with this, this cold-rolling mill safeguards that replacing pressure roller is simple and convenient, save cost, improve effect.
